Examples

Pea-Gravel Banks: Bass love to spawn on hard, clean, pea-gravel bottoms, which are usually most prevalent in creek arms and coves on the lower (or deeper) ends of reservoirs where siltation is less common.

Coral reefs: Recent estimates indicate that approximately 20% of coral reefs have been lost, with an additional 20% having been degraded in the last several decades of the twentieth century, through impacts such as siltation and destructive fishing practices.

Other major disturbances are habitat alteration caused by hotel and marina construction; nutrient enrichment from run-off of agrochemicals that are increasingly being used on banana and citrus plantations and from sewage pollution from tourist resorts and residential and urban centers; erosion of the shoreline by removal of vegetation including mangroves and seagrass areas; and choking of corals by siltation resulting from dredging and sand mining.

Angola's major environmental issues include: overuse of pastures and subsequent soil erosion attributable to population pressures; desertification; deforestation of tropical rain forest, in response to both international demand for tropical timber and to domestic use as fuel, resulting in loss of biodiversity; soil erosion contributing to water pollution and siltation of rivers and dams; inadequate supplies of potable water.

Already the feeder streams of the Upper Lake have been taken up for de-siltation and a similar campaign was launched at Ujjain, another major town of the province, followed, though, by disconcerting reports.
